[Cliffdwellers] Multiband Apartment Antenna for 10-12-15-17-20

[Tim Billingsley]

A friend(new general) has just accepted a job in Nashville and will have to
setup housekeeping in an apartment. He primarily works Phone, PSK31, and
some CW on 10-12-15-17-20.

Any suggestions(tried and true or just ideas) on a suitable antenna for him?
